Highlights

Rugged 500W pond de-icer boasts stainless steel construction

Effectively prevent pond surfaces from completely freezing

Maintain an open area during winter for vital pond gas exchange

Overview

Rugged, stainless steel pond de-icer ensures season after season of reliable performance. Made from durable stainless steel, the 500 watt Laguna Power Heat boasts high impact resistance over competing plastic pond de-icers. The tough exterior houses four thermo-sensors that sense water temperature from different locations within the unit. This smart technology allows for accurate thermostatic control even in freezing conditions, 20 degrees Fahrenheit and below. The Laguna Power Heat effectively prevents pond surfaces from freezing completely to allow crucial gas exchange. Safe for plastic and liner ponds and features a highly-visible LED light that indicates proper function of the unit. 22 ft electrical cord with grounded plug. 7-1/2" dia x 5" high.

More Information

Installation InstructionsWarning: Extreme caution should be taken when working near frozen ponds. Never walk on thin ice. Your safety should always be of the highest priority.

The de-icer should be positioned over the deepest part of the pond.

Place the unit in the pond. Once the unit is in the pond, plug the cord in the electrical socket. If the pond surface is already frozen, proceed with the following:

Fill a pot of suitable size with boiling water. Attach a cord or string to it and place it on the frozen surface. The hot pot will eventually melt a hole through the ice surface. Once a suitably large hole is created, install the unit. Never break or chop at the ice as the shock waves can unnecessarily stress pond fish.

The primary function of a de-icer is to maintain a small opening at the surface of the pond to allow efficient gas exchange.

Cleaning Instructions
After use, begin by unplugging the de-icer. Remove from pond and clean the unit thoroughly using a bio-degradable detergent in conjunction with a scrubbing pad. Rinse well and dry completely before storing.

General Information
This Laguna winterizing product will keep an area thawed and open in the pond, allowing the release of toxic gases from fish respiration and decomposing organic matter to escape which is essential for fish survival. At the same time it allows oxygen to re-enter the pond.

When I purchased this heater my pond was almost all ice except where the water falls is. Once I placed in pond, the ice melted and my fish were happy . I live in Philadelphia and we have had a very cold Feb. So far, the ice is gone.

Rated 5 out of 5 by Eddie346 Great De-icer
This de-icer works well to maintain an opening in the ice in winter. Best of all, the LED lights tell you when it is heating and when it is in the "standby" mode. It also has an extra long cord which allows you to place it out in the middle of your pond. On my unit the green light indicates it is heating, while the red light indicates "standby" mode. (On the internet it is the opposite).

Rated 5 out of 5 by Magnolia64 Life Saver!
I live in North Carolina and we have had an extremely cold winter this year. I have had a water garden for 9 years and never needed a de-icer. I always keep my filtration running and I have a "Jan made" (instead of man made) stream flowing into it. That usually has created enough water movement to keep my pond from freezing. Well not this year! Temperatures plummeted and then the snow came. I have never been so stressed. I went online and began reading the reviews of many de-icers. Yes there were some less expensive on Drs Foster but the reviews were not as good. I didn't want to put my fish through unnecessary stress nor myself so i went with this one. ALL reviews were good with it. It is light and durable, sleek in appearance and it has a neat indicator light on top that is easily visible. It immediately began defrosting and this water had ice approximately 3 inches thick. Thank you Drs Foster & Smith for once again making my ever so loved project a worry free pond.

I have a 1050 gallon pond and current de-icer has raised my electric bill quite extensively. I has been quite cold here and in the freezing and below temps for an extended period, however last year winter was quite warmer and still raised my electric bill by $90.00. I presently own the one that either floats or sinks. Last year it was sunk and this year floats, but still have exhortbintly high bills. Need to find a more efficient one, and wonder if this is the one?

This de-icer only comes on when necessary. It is a floating deicer, not a pond heater. It maintained a hole in the ice with temps here in PA in the single digits, and the unit was rarely in the "heat" mode, so it doesn't use huge amounts of electricity. The LED lights tell you when it is heating and when it is not.

I just bought the 500W heater as the 1250W that I had broke. And yes my electric bill was sky high. So hope this new one is better on the electric draw. I also a have Air Pump, so between the two they work fine. My pond is 2000 gallons in Boston area.

Thank you for your question. Unfortunately, it is all going to depend on how much the de-icer ends up running. Depending on what the de-icer you own, it's possible you have one that is running something like 1500W (the one I found currently on our site that either floats or sinks is a 1500W), which could explain the huge hike in your bill. This de-icer is 500W, which means it wouldn't be using such a high amount of energy, making it more energy-efficient than a 1500W.

Answer:

I'm in PA and I use both a bubbler and a de-icer. The de-icer maintains a hole in the ice by itself, but the bubbler circulates the water and helps the ammonia escape. I run the bubbler all year round. If you decide to add a bubbler, choose one of good quality and buy large air stones and tubing. It's well worth the investment.

I have a bubbler also. That's keep a fairly large area open, but when the temp hits sub zero; the water freezes over. So you also need a heater. I have used the 1250 watt heater for 10 years until it just stopped working this year. I try to only use it when the weather is sub zero as it jacks up the electric bill. I just got the 500W heater and that seems to work fine. My pond is about 2000 gallons and I am in Boston.

Thank you for your question. De-icers are used to maintain an opening in the ice for vital gas exchange. Because your pond is so large, we also suggest using an aerator to keep the water moving so it does not freeze. The PondMaster Deep Water Air Pump, item number 24871. Here is a link to this aeration pump:

I have a 500-600 gallon cement basin fountain. I don't have any fish (yet) and the surface of the fountain is frozen solid. Will this unit thaw a hole to the water, or does it need to be placed in open water?

Drs Foster and Smith Articles

Having an area free of ice is crucial for koi ponds or ponds with fish to allow proper gas exchange. Without an opening in the ice the supply of dissolved oxygen is depleted. Use our de-icer comparison chart to chose the right de-icer for your pond.

Getting your pond ready for winter really begins in the fall. Water temperature, rather than air temperature, is the important indicator of when it's best to make changes to your pond. Use our Winter Survival Guide to get prepared for the season.

As winter approaches, you will want to make sure your pond system is clean and operating at 100% efficiency. You will also want to make sure that the water quality is as good as it can be. Use this article to learn how.
